This sounds great and seems like a 'no brainer' if you grew up in the desert. I wonder why these studies don't focus more attention on current infrastructure though. Urban buildings have equally massive footprints and are already on the grid. The entire urban highway system of blacktop is tied to the grid and acts as a thermal mass, increasing ground temperatures and contributing to the heat island effect. Why not cover it?
